HYDE PARK (CBSLA.com) — Los Angeles police are seeking the public’s help as they search for a hit-and-run driver who left a 35-year-old man severely injured in Hyde Park.

According to friends, the victim is Mikail Hasan, a member of a motorized bicycle club.

They said Hasan had just left for a short test drive on one of the motorized bikes when the collision happened around 3:40 p.m. on Monday.

Security video showed the victim going west on 48th Street when a burgundy Oldsmobile Cutless made a left turn onto 9th Avenue and into the path of the motorized bike.

Hasan slammed head-on into the side of the Oldsmobile, sending him airborne.

The driver, who was with a male passenger, failed to stop and render aide to the victim, who was later taken to a hospital where the father of nine was listed in critical condition.

“I actually got down there with him on the ground and held his hand. He was kind of moving around,” a friend said. “It’s terrible. It’s sad. Watching the tape earlier on the news, the whole car shifted to the left. You know something hit you or you hit something,”

The victim’s friends are heartbroken over what happened. They have a message for the man who was driving the car and his passenger.

Friends said Hasan was not wearing a helmet because he figured it was a quick ride.
